Microquanta

Microquanta has announced the completion of what it claims to be the world's largest building-integrated photovoltaic (BIPV) project based on perovskite solar panels. Installed on the translucent roof of the University Student Entrepreneurship Center in Shenchi County, Shanxi Province, the project has a capacity of 17.92 kWp. 

Microquanta specified that its custom-designed double-glass perovskite modules measure 1,200 mm x 1,000 mm and achieve a light transmittance of around 40%, allowing daylight into the building interior while generating electricity.

Microquanta has reportedly announced that its 810 cm² medium-sized perovskite module has achieved a certified full-area power conversion efficiency of 21.86% (average of forward and reverse scan: 21.83% forward, 21.89% reverse), as verified by the National PV Industry Measurement and Testing Center (NPVM).

The company called this a new efficiency record for perovskite modules of this size. Microquanta stated that the module incorporates its proprietary cryogenic laser repair technology, which in addition to significantly enhancing module efficiency also greatly improves module stability. Microquanta plans to apply this technology to its upcoming GW-scale perovskite production line, set to commence operations in March this year. The company has set a target of surpassing 20% conversion efficiency and achieving a 25-year lifespan for large-area modules with a size of 2.88 m².

Microquanta has announced that a 1 MW solar rooftop demonstration project at Qinghai University has been successfully grid connected. The project makes use of Microquanta’s perovskite modules and is one the first megawatt-scale perovskite rooftop distributed PV projects in Qinghai Province. The electricity generated by this rooftop plant will be utilized by the campus. 

This project is said to be one of the largest perovskite power plants globally. It is equipped with a smart monitoring platform, which provides real-time visualization of the plant’s power generation, electricity transactions, and equipment performance. Over its 25-year lifecycle, the project is expected to generate a total of 20,327,745.20 kWh, with an average annual output of 813,109.81 kWh.

MicroQuanta has reportedly announced the successful grid connection of an 8.6 MW ground-mounted PV plant in Lishui, Zhejiang province, China. The plant in eastern China – the world's largest to be built with perovskite solar technology – focuses on agrivoltaics.

The facility sits on previously unused land in Songyang county and features 95,648 MicroQuanta α perovskite modules. The 90 W modules measure 1,245 mm x 635 mm and weigh 12.5 kg. The panels are tilted at a 22-degree angle, utilizing the terrain's natural slope. To allow agricultural use beneath the solar arrays, the lowest edge of the panels are elevated 2 meters off the ground.

It was reported that China-based Microquanta has shipped its self-developed 50 MW perovskite α modules to China Huaneng for a PV demonstration project, reportedly marking China’s first commercial use of four-terminal perovskite-silicon tandem modules. 

The 1,245 mm x 635 mm modules feature perovskite layers on tunnel oxide passivated contact (TOPCon) cells, achieving a power conversion efficiency of 25.4%.

Microquanta has reportedly achieved a conversion efficiency of 23.65% on small perovskite solar modules, certified by Fujian Metrology Institute.

The perovskite module has an area of 19.38 cm², achieved using its proprietary frozen laser repair technology. It is said to exhibit exceptional photo-thermal durability, with less than 5% efficiency degradation even after exposure to cumulative UV aging doses far exceeding the IEC 61215 standard (200 kWh).

Microquanta, a perovskite solar cell manufacturer based in Hangzhou, China, has announced its latest procurement of state-of-the-art vacuum deposition equipment from SMIT Thermal Solutions. This significant acquisition, surpassing 9 million Euros in value, marks a pivotal moment in Microquanta's journey towards launching the world's first gigawatt-scale (GW) perovskite solar cell factory in Hangzhou.

This collaboration with SMIT Thermal Solutions is not a first for Microquanta; the Dutch-based company has been a partner since 2018, starting with a pilot setup, followed by the delivery of a mass production system for Microquanta's 100MW factory. The latest deal involves cutting-edge next-generation mass production systems, tailored to meet the ambitious scale and efficiency goals of Microquanta's GW factory.

Microquanta has reported that its novel perovskite-based PV power station is now connected to the grid. The Company referred to it as a "perovskite commercial rooftop power station", erected over the water for fish farming applications. 

The perovskite power station is located in Qujiang district, Quzhou City, which is rich in water sources and farming. According to local conditions, it adopts the "onboard power generation and offboard farming" model. The installed capacity of the first phase is around 260 kW. The owner is Qujiang Construction Investment. 

Perovskite solar developer Microquanta and Xiaer Tela, a company specializing in floating PV applications, recently signed a strategic cooperation agreement to develop water surface perovskite applications and various floating solar products. 

The Companies will jointly develop perovskite PV related products and power generation systems suitable for inland and offshore floating, and provide full-cycle support and services.

Perovskite solar panels have been under intensive R&D, and it seems as if commercial production is right around the corner. Some pilot-scale production lines are already functional, and companies are now ramping up production of perovskite panels, using various technologies.

UK-based Oxford PV, for example, recently announced that it has completed the build-out of its 100 MW manufacturing site in Germany, and it is on track to start full production in 2022. China's Microquanta Semiconductor perovskite panel factory is reportedly also nearing production (which should have started late 2020, but updates have not been available since), and another China-based company, GCL, has raised around $15 million USD to expand its pilot-scale production factory to mass production (100 MW).
